For Filtration of Fruit JuicesSeitz FA series depth filter sheets were developed to meet the production needs and requirements of the fruit juice industry and associated applications requiring thermoacidophilic bacteria (TAB) spore control.
The FA filter sheets combine the process mechanisms of surface filtration, depth filtration and adsorption to fulfill the specific requirements of fruit juice, juice concentrate and ingredient manufacturers.
FA filter sheets are available in multiple grades suitable for polishing, clarification and microbial reduction.
|Homogenous and consistent media, available in four grades|| |
|A combination of surface, depth and adsorptive filtration|| |
|Each individual filter sheet is laser etched with the sheet grade, batch number and production date.||Full traceability|
|FA 05||Reduction of microorganisms prior to storage of fruit juices and concentrates or prior to final bottling|
|FA 10||Polishing filtration of clear fruit juices prior to bottling, to achieve brilliant products, especially for apple juice filtration|
|FA 20||Polishing filtration prior to bottling, when high throughputs are required|
|FA 30||Clarifying filtration of colored juices such as red/black currant or cherry juice; clarifying filtration of apple juice|

These figures have been determined in accordance with in-house test methods and the methods of the Technical / Analytical Work Group within the European Depth Filtration Association.
2The permeability was measured under test conditions with clean water at 20 °C (68 °F) and a Δp of 1 bar (14.5 psi).
RegenerationFA series filter sheets may be rinsed with clean water (in the forward or reverse3direction) to increase throughput and to optimize economic efficiency. Optimal regeneration of filter sheets installed in a plate and frame filter may be achieved with serial rinses of warm water followed by hot water. An example protocol is shown below.
- Rinse with warm water (60 °C / 140 °F) for 15 minutes
- Rinse with hot water (70 – 80 °C / 158 – 176 °F) for 8 – 10 minutes
3When rinsing in the reverse flow direction it is critical to control particulate and microbial levels in the rinse water so that the filtrate side of the sheet is not contaminated. Water used for reverse flow flushes should be particle-free, and if the filter will not be sterilized prior to re-use the water should be free of microbes. Backwashing should be in a diagonal direction from outlet to inlet in a plate and frame filter.
